3D flat panel printer sprays UV ink. Is UV ink toxic?

Whether UV ink is toxic or not depends on the specific composition of the ink. Traditional UV ink contains solvents, which may be toxic. However, in recent years, more and more UV inks adopt solvent-free or low-solvent formulations. These inks are safer and more environmentally friendly.

The following are some common UV ink ingredients and their toxicity:

Photosensitizer: Photosensitizer will polymerize under ultraviolet radiation, thus curing ink. Photosensitizers are usually nontoxic.

Polymer: Polymer is the main film-forming substance of ink, which determines the performance of ink. Polymers are usually non-toxic.

Pigment: Pigment determines the color of ink. Pigments may also contain toxic substances, such as lead, cadmium and mercury.

Solvent: Solvent is used to dissolve pigments and polymers, which makes ink have fluidity. Solvents may be toxic, such as benzene, toluene, xylene, etc.

Therefore, when choosing UV ink, we should pay attention to the composition of the ink. If the ink contains solvent, you should choose low solvent or solvent-free formula.

In addition, when using UV ink, pay attention to safety. When using UV ink, gloves, masks and protective glasses should be worn to prevent skin, respiratory tract and eyes from contacting toxic substances.
